Tabx

Tabx is a modular software framework for building tab-based user interfaces in cross-platform applications. It provides reusable components for tab containers, panels, and content panes, along with a light state manager and event API. The design emphasizes performance, accessibility, and interoperability across web and native environments through adapters.

Tabx originated in the early 2010s as an open-source project by a collaboration of developers seeking a standard approach to tab navigation in complex dashboards. The initial release appeared in 2014 on a public repository and evolved with a plugin system and accessible defaults.

Core features include a tab manager for creation, reordering, and closure; lazy loading of tab content; keyboard navigation and ARIA support; theming and style customization; and a plugin API for extending tab types and data renderers. Bindings exist for web frameworks and native toolkits, supporting desktop and web use.

Usage reports show Tabx in internal dashboards, data exploration tools, and educational software. Proponents note its lean footprint and straightforward API, while critics point to fragmentation in adapters and the need to synchronize plugin versions across projects.

Tabx is maintained by an open-source community and is designed to be compatible with established tabbed-interface patterns.
